Though nothing is certain, the patent indicates Amazon is working on a way for autonomous vehicles to communicate with highway management systems to handle surges in traffic flow and navigate changes in variables such as speed limits and passing laws in different states.

Interestingly enough, the patent isn’t only restricted to cars. The patent also covers “any type of vehicle, including but not limited to cars, trucks, vans, buses, street cars, helicopters, trains, subways, aircrafts, boats, etc., regardless of how powered or driven." The system outline in full:

The network would be owned and operated by Amazon, but would theoretically be open to and able to communicate with almost any autonomous vehicle regardless of owner or manufacturer.
